One of the best "dark rides" ever.
Don't ride it if you have any back or neck problems, it's quite jerky and not worth aggrevating any current problems you have.
I don't recommend this ride for small children. It can be very intense. My son, at 7 will ride the haunted mansion if I ask, but when I explain that this one involves large dinosaurs he alwaysd passes. I'll try again next time, but I can wait.
Otherwise, it's a "must do".
